My said invention relates more particularly to the link joints tor chalns tor-con-* ncctingthe individual lin'kswith each other. i

The invention has among its objects to provide a pix' otjoin't which/will be strong and durable and in which the wear on the parts will be" reduced to aminimumydue to the use of hardened metal partsto;-receii e" the wear and the'pro'vision of effective lubr'reating means; 1

The invention includes the novel features of construction and arrangement androin bination of parts hereinafter described and" particularly defined by thefappendedclaims.

In order that the-invention may 'be'niore readily understood, I'have appended hereto a drawingillustrating the same in'whichr Fig. 1 is a sectional plan view oftwo connrcted linl'rs-torming part of'a chain} FigJQ is a sideelevation of the same;

As the bushing 3 isof hardened steel overlapping links and their peripheries bear ,agaiiist-tlie walls ol therecesses, being held J in contact therewith-by the-inner' bushing 3,

These overlapping parts are proin which event said arc-shaped bushingsarc vided with circular aligned openings 1 the relied on to hold the links in juxtaposition. walls of which may be cylindrical as shown In this form I have shown how the inner in Figs. 1 to 8 and within which are placed bushing parts (which correspond to the elea pair of arc shaped bearing bushings 0t ments 3,3 of Fig. 3) may be made integral hardened steel as indicated at 2, 2. with the side plates l as indicated at 3.

These bushings are made of a thickness Inthis form the connecting element 5 is corresponding. to the thickness of the two formed as an independent rivet headed over Figs. 5 and "6. are transverse sectional vented from shifting around-int0contact I H ""shown 'i'n Fig. in which 'eventtheplates would, of course,- also be'made of soft metal. 7 The spaces "between the arc-shaped bush as indicated at 3, Figs 4, in which event the being composed of juxtaposed plates 1 conveniently of sheet metal having forked or separated portions cl to receive between them {the cooperating end of the next adjoining link.

The overlying portions of the links are provided with aligning openings to receive the bushings and rivets, the bushings being shown at 2 and 2 and the rivet at 5 a cylindrical sleeve or wear receiving bushing 7 being interposed between the rivet and are shaped bushings, the parts being confined in place by the side plates or washers 1. The bushing 2 is provided with an integral projection cl designed to engage'a corresponding recess in the abutting portion oi the corresponding link and the bushing 2 is provided with a recess 6 designed to be engaged by projections on the forked portion of the adjacent link.

The bushings are provided with beveled flanges (Z and e and the openings in the walls of the links are correspondingly beveled.

In the form shown in'Figures 11 to 16 inclusive I make the openings in the link walls cylindrical and omit the beveled flanges from the bushings, making these of the shape of the segment of a plain cylinder as indicated at 2 Fig. 13. In this form each link portion has two projections f designed to abut against opposite ends of the bush ing as shown in Fig. 11. The cylindrical sleeves, rivets-and washers or side plates for both the forms shown in Figs. 7 and 8, and 11 and 12, are shown in detail in Figs. 13, 14, 15 and 16 respectively.

The links may be provided with outwardly turned or enlarged portions to recfive wear plates 9 to engage the sprocket teth.

As will be evident to those skilled in the art, my invention permits of various modifications without departing from the spirit thereof or the scope of the appended claims.

This application is based upon my application No. 463,833, filed April 23, 1921, allowedNovember 2, 1922, and now held among the abandoned files.

Having thus described my invention, what I claim is:

1. In a link belt or chain joint, a pair of overlapping links having aligning openings, a pair of arc-shaped bushings within the openings, a wear receiving bushing between said arc-shaped bushings and side plates connected together and overlapping said bushings and links.

2. In a link belt or chain joint, a pair of overlapping links having aligning openings, a pair of arc-shaped bushings within the openings, a two-part wear receiving bushing between the arc-shaped bushings and having outer parts countersunk into the same, and connected side plates overlapping said bushings and the adjacent portions of the chain links and closing the space between said arcshaped bushings.

3. In a link belt or chain joint, a pair of overlapping links having aligning openings, a pair of arc-shaped bushings within the openings, a two-part wear receiving bushing between the arc-shaped bushings, having outer portions countersunk into said areshaped bushings, side plates overlapping said bushings and the adjacent portions of the chain links, and a rivet integral with one of said plates and engaging the other plate for holding them together.

4. In a link belt or chain joint, a pair of overlapping links having aligning openings, a pair oi arc-shaped bushings within the openings, a wear receiving bushing between said arc-shaped bushing and side plates connected together and overlapping said bush-. ings and links, said side plates'having annular recesses, and packing rings inserted in said recesses and bearing against the outer faces of the chain links.

In testimony whereof, I at ix my signature.
